Mahon, Norristown, Pa., assignors to Container Corporation ofAmerica, Chicago, III., a corporation of Delaware Filed Feb. 27, 1962,Ser. No. 175,977 12 Claims. (Cl. 229-40) This invention relates tomulti-pak cartons formed of paperboard, and more particularly to an openend sleevetype carton for holding two parallel rows of generallycylindrically shaped objects, such as cans or bottles, arrangedin'side-by-side relation.

The invention comprehends an improved center retaining member on onewall of the carton adapted to restrict the movement of the containersrelative to said carton wall.

An object of the invention is the provision of a tubular carton of thetype described, formed from a unitary blank of foldable paperboard,having an integral center retaining member.

A more specific object of the invention is to provide, in a carton ofthe type described, an integral center retaining member, formed from endportions of the panels of one wall of the carton, having recesses forreceiving portions of the packaged articles to restrict their movementrelative to said one carton wall.

These and other objects of the invention will be apparent from anexamination of the following description and drawings, wherein:

FIGURE 1 is a perspective view of a carton embodying features of theinvention;

FIGURE 2 is a horizontal section taken on line 2-2 of FIGURE 1;

FIGURE 3 is a fragmentary transverse vertical section taken on line 3--3of FIGURE 2;

FIGURE 4 is a plan view of the blank from which the carton illustratedin FIGURES l to 3 may be formed;

FIGURE 5 is a fragmentary view similar to FIGURE 1, but illustrating amodified form of the invention;

- FIGURE 6 is a perspective view of a portion of the center retainingmember of the carton illustrated in FIGURE 5;

FIGURE 7 is a transverse vertical section taken on line 7-7 of FIGURE 6;

FIGURE 8 is a plan view of the blank from which the carton illustratedin FIGURES 5 to 7 may be formed;

FIGURE 9 is an end elevational view of a carton illus trating anotherform of the invention, with portions of the structure shown in verticalsections;

FIGURE 10 is a horizontal section taken on line 1010 of FIGURE 9;

FIGURE 11 is a fragmentary plan view of a portion of the blank fromwhich the carton illustrated in FIG- URES 9 and 10 may be formed; and

FIGURES 12 and 13 are fragmentary views similar to FIGURE 9, butillustrating yet other forms of the invention.

It will be understood that certain elements have been intentionallyomitted from certain views where they are illustrated to betteradvantage in other views.

Referring now to the drawings for a better understanding of theinvention, it will be seen that one embodiment of the invention isillustrated in FIGURES 1 through 4.

As best seen in FIGURE 1, the carton includes a pair of spaced paralleltop and bottom walls 10 and 12, respectively, interconnected by a pairof spaced parallel side walls 14, which have their opposite edgeshingedly con nected to the top and bottom walls along parallel cartonhinge lines 16.

Bottom wall 12 is formed from a pair of co-planer bot- 2 tom wall panels18 having their outboard edges hingedly connected, along hinge lines 16,to corresponding bottom edges of the respective side walls 14, andhaving their inboard end portions folded and interconnected to form aninwardly projecting center retaining member 20 extending longitudinallyof the carton between two parallel rows of packaged articles.

At its inboard edge, each of the bottom wall panels 18 has hingedlyattached thereto a longitudinally extending relatively narrow firststrip 22 which is folded inwardly along fold line 23 and projectsinwardly into the carton at approximately right angles to panel 18.Opposed surfaces of the respective bottom wall panel strips 22 may besecured to each other in any desired manner, such as by the applicationof adhesive therebetween.

At its inner or upper edge each first strip 22 has hingedly attachedthereto along a hinge line 24 a downwardly and outwardly projectingrelatively narrowlongitudinally extending second strip 26. Second strip26 is of preferably the same general dimensions as first strip 22, butat its lower or outer extremities is provided with a plurality ofrecesses 28, the purpose of which is described later in thespecification.

It will be noted that the carton illustrated in FIGURES 1 through 3 ofthe drawings may be formed from the unitary blank of foldablepaperboard, indicated generally at 30, shown in FIGURE 4 of thedrawings.

If desired the top wall 10 may be provided with a plurality of fingerholes 32 to aid in handling of the carton. Also, both the top and bottomwalls may be provided with a plurality of chime engaging tabs 34 cutfrom the respective walls of the carton and folded inwardly intoengagement with the ends of the cans. This feature is not new in theart, and is therefore not directly connected to the invention whichforms the basis of this application.

The basic purpose and function of the center retaining member 22 is bestillustrated in FIGURE 3 of the drawings, which shows the relationship ofthe second strips 26 of the chimes C of the cans K located within thecarton. The recesses 28 in the center retaining member second strips 26serve to receive end portions of the cans within the carton, with thedownwardly facing abutment surfaces 36 presented by the second strips 26in the recesses 28 serving to engage the upwardly facing surfaces of thecan chimes so as to restrict movement of the cans relative to thebottomwall 12 of the carton.

Now turning to FIGURES 5 through 8 of the drawings, it will be seen thata modified form of the invention is shown therein. In this embodiment,many of the features are common to those of that previous embodiment, sothat, where possible, corresponding numerals have been used to designaterelated elements.

The primary distinguishing feature of this embodiment resides in theconstruction of the central retaining member, best seen in FIGURE 6 ofthe drawings. In this arrangement the second strip 26a of the centerretaining member 20a has hingedly attached, at locations between therecesses 28a, a plurality of flaps 40 which are hingedly attached to thelower edges of the strips 26a along fold lines 42. Flaps 40, if desired,may be adhesively secured to the upper surface of the related bottomwall panels so as to limit their movement relative to the bottom walland thereby make a more rigid structure the center retaining member 20a.9

This carton like that of the previously described embodiment isparticularly well suited for chimed cans, and functions in the samemanner as the previously described embodiment.

Now turning to FIGURES 9 through 11 of the drawings, it will be seenthat another embodiment of the invention is shown. In this embodiment,the carton is suitable for 'use with unchimed cans, or cans havingchimes at only one end thereof, as well as for other cylin- ,to theirlower or outer edges, along fold lines 52, relatively narrowlongitudinally extending third strips 50. Third strips 50 are bentinboardly toward first strips 22b of their respective bottom wall panelsso as to lie under the second strip 26b in parallel abutting engagementwith the upper surfaces of their respective bottom wall panels. Ifdesired they may be secured in any desired manner, such as by adhesive,to their respective bottom wall panels.

In this embodiment of the invention, the respective second strips 26b ofthe center retaining member 20b are provided with a pluralityoflongitudinally spaced generally arcuately shaped recesses 28b whichserve to receive and retain end portionsof the packaged articles so asto restrict their movement relative to the bottom wall of the carton.

In FIGURE 12 another embodiment of the invention is disclosed. In thisembodiment, which is similar in certain respects to the embodimentillustrated in FIGURE 9, the bottom wall panels 18c of the carton aresecured to each other in overlapping relationship, with the centerretaining member 200 being formed entirely from one of the bottom wallpanels 18c. In this embodiment the uppermost or innermost bottom wallpanel 180 has hingedly attached to its inboard edge, on a fold line 62,an inwardly extending first strip 60. Strip 60 has, hingedly attached toits upper edge, on a fold line 64, a downwardly extending second strip66 which, in turn has hingedly attached to its lower or outer edge, on afold line 69, a third strip 68. Third strips 69 may be secured in anydesired manner, such as by adhesive, to the upper .surface of the otherbottom wall panel 18c. In this embodiment both the first and secondstrips may be provided with longitudinally spaced recesses 28c for thereceipt of lower portions of the packaged articles.

The embodiment of FIGURE 13 is similar to that of the previouslydescribed embodiment, with the center retaining member 20d being formedentirely from one of the bottom wall panels 18d.

In this embodiment a first longitudinally extending strip 70 is hingedlyattached, along fold line 72, to the inboard extremity of one of thebottom wall panels 18d. The first strip extends upwardly or inwardlytoward the center of the carton and has hingedly attached, thereto on afold line 74, a second strip 76 which extends downwardly or outwardlytoward the bottom wall of the carton and which has hingedly attached, ona fold line 79, to its lower or outer edge'a third strip 78. Third strip78 may be secured in any desired manner, such as by adhesive, to theupwardly facing surface of the same bottom wall panel 18d to which thefirst strip is attached.

In this-embodiment, like the previous embodiment, both the first andsecond strips may be provided with longitudinally spaced recesses 28dwhich serve to retain lower orend portions of the packaged articles.

Although in each of the cartons illustrated and described, the centerretaining member is formed from coplaner panels of the carton bottomwall, the entire arrangement could, if desired, be reversed, with thebottom wall being formed as a single panel and the center retainingmember being formed from co-planer panels of the top wall.

Thus. it will be understood, that in each of the embodiments of theinvention heretofore disclosed and described, one wall of the carton isformed from a pair of coplaner panels having inboard portionsinterconnected and folded to provide a center retaining member withlongitudinally spaced recesses adapted to receive portions of thearticles packaged within the carton and thereby restrict the movement ofthe articles relative to the wall of the carton.
